SERVICE PROCEDURES (Continued)
CRANKSHAFT MAIN BEARINGS
The crankshaft is supported in five main bearings.
All upper and lower bearing shells in the crankcase
have oil grooves. The number three lower main
thrust bearing is plain. Crankshaft end play is con-
trolled by a flanged bearing on the number three
main bearing journal (Fig. 11).
Upper and lower Number 3 bearing halves are
flanged to carry the crankshaft thrust loads and are
NOT interchangeable with any other bearing halves
in the engine (Fig. 11). All bearing cap bolts removed
during service procedures are to be cleaned and oiled
before installation. Bearing shells are available in
standard and the following undersized: 0.025 mm
(0.001 in.), 0.050 mm (0.002 in.), 0.250 mm (0.010
inch.) 0.275 mm (0.011 inch.) 0.300 mm (0.012 inch.).
Never install an undersize bearing that will reduce
clearance below specifications.
